$I.$ S-phase - $DNA$ replication
$II.$ Zygotene - Synapsis
$III.$ Diplotene - Crossing over
$IV.$ Meiosis - Shown by haploid and diploid cells
$V.$ $G_{2}$-phase - Quiescent stage
The second stage of prophase$-I$ is called zygotene. During this stage, chromosomes start pairing together and this process of association is called synapsis. Such paired chromosomes are called homologous chromosomes. Synapsis is accompanied by the formation of a complex structure called synaptonemal complex. Crossing over happens in PAchytene. Meiosis occurs only in diploid cells. Go phase is the quiscent phase
